Abstract
A transmission apparatus has two components that move in translation relative to one another and a coupling gap between the components containing a magnetorheological medium. The gap is formed and sealed outwardly at first and second ends so that the magnetorheological medium remains in the coupling gap as a sort of controllable friction lining, irrespective of a coupling between the components, in accordance with the magnetic field applied in the coupling gap. One of the components has plurality of radially extending arms that carry a magnetic field generation device. Each magnetic field generation device has an electric coil with a least one winding extends completely beside the central axis and at a distance therefrom. Different poles of the magnetic field generation devices are provided at the adjacent ends of adjacent arms of a component. The coupling gap is connected to a reservoir of magnetorheological medium.
